Login "async" Remote Address

Hi,

we have ACS 5.3 and I don't know why we have a lot of authentication failed of of Username like:

  1. "state to down"
  2. "d state to up"
  3. "% Authentication failed"
  4. "l1/0:15, changed state to up"

All logs have "async" in the Remote Address field

The followng is an example of the log:

Login "async" Remote Address

Did you ever figure this out?

Login "async" Remote Address

can you please tell me what device they are coming from? The async port is a console port. Once you find the NAS ip address,please get it physically checked what is connected on Console port, even if we have a console cable connected remove it. It seems like there is something that is causing a noise on console port (tty0).

On the NAS device, please use "show line" and check if there is noise appearing on the console port.
